l iwonnnrnn, of the city of phia. and

State of Pennsylvania, have invented certain the following is a speeitication. y p .p ',Ylin-vention relates tothat class oi' wrenches which n adjustable handle '6F lever susceptible of lbeing 4ienceof manipulation. a. v

Vlllheynature of theinvention consistsof a jaw-head,

l lnfoilidcd with a circular rack, in combination with `a '.leverhaving a fixed. catch, `which engages with the p teeth ofthe rack, the saidlever havingaswivel movegm'ent, by means of alink connection with the jaw-head, nshereinafter described. i

" i To enable others skilled in the fart fto which 'my improvement appertains tol make and use my invention, --11 will` now give a detailed description thereof.

l VIn. the accompanying drawing which makes a nart 'Figure 1 is a side view of theimproved wrench.

vFifgure 2 isian edge view of the same.' 4

. Like letters in" both figuresindieatc the same parts.

,A is the jaw-h`ead, and

Bg-,the lev'er or handle; p The said parts are connected together by means of thel links C- C and pnsDDC i. n

j In adaptation to Various sizes of nuts, a number ofl heads, A, having,r different sizesof openings, 1,accom- 'panics the lever B.

loprovidc for the changing of the heads, the counecting-pin D has a nut, c, on one end, \vhereby it `is expeditiously removed and reconnccted.

l 'lhejaw-head A isprovided with a circular rack, f,

Philadelin which the catch g on the lever B is engagedby-the movement'of the lever as it Yis 'brought from the posiby dotted lines in fig. 1. It will be seen that changes in lthe position of the tion represented by full lines tothe one represented` vlever B, with the jaw-head A andnnt h, to be turned -its head Aby a swivel movement.

for convenience of manipnlation,are effected by changg with different teeth inDr the connection of the catch of the raekf. .Y

I am aware that various modes have been adopted for varying the position of the lever of a `wrenclrwith lhey have been, however, of a complicated character, and have em# braced la movable catch or pawl for holding the lever in position with the head. By getting rid'oi this feat' ure, and making the catch g and lever B iu a single y piece, as represeuted, great firmness in'the wrench? is 1 obtained, and liabilityv of getting-out of order obviated. f What I claim as my invention, and desire 'to se; ure by Letters Patent, isv 1.V The combination of the head vided with a catch, g, ranged and operatinr substantially in the manner and for the purpose set forth. Af.

.2. The construction of the lever B with a'stationarycatch g, substantially as described. p

In testimony that the above is my invention, Ihave hereunto set my hand and afiixed my seal, this 23d day of' April, 1870.
